Free Trial Upgrade To Paid
Allow users to upgrade from Free Trial to Paid before the end of the free trial. In a software subscription model, a user may do a 30 day free trial where they receive a trial license. They may be ready to purchase after 10 days, and want their full license. There is no option in Zoho Subscriptions for the user to activate their subscription before the end of the free trial
